“[A] master of the classic puzzle.”—The New York Times Book Review “Lovesey’s delicate balance of humor and suspense [is] one of the delights of contemporary crime fiction.”—The Wall Street Journal “A master storyteller.”—Kirkus Reviews Widowed Inspector Peter Diamond is being pursued by a secret admirer as he pursues a serial killer. Delia Williamson, a mother of two young girls who works as a waitress, is first reported missing by her own mother. She is found in a public park, hanged from the crossbar of a children’s swing set. There seems to be no reason for her to have committed suicide, and the postmortem reveals that she was murdered. Her present partner, her ex-husband, and a traveling salesman who dined at her table in the restaurant where she worked, are all suspects.
